IMPROVEMENT IN' LUBRICATRS.

The Schedule referred to in these Let-ters Patent and making pan of thesame.

the accompanying sheet of drawings, and to the letters of referencemarked thereon.

Our invention relates to regulating the flow of oil or other lubricantfrom an oil-cup, to the parts to be lubricated.

On reference to the accompanying sheet of drawings, making part of thisspecication Figure l is a sectional front view, and

Figure 2 is a sectional side view.

Similar letters refer to similar parts in the two views.

The general external form is that1 of the ordinary oil-cup, of the mostapproved construction.

The. internal mechanism which regulates theiflow of the lubricant is asfollows:

The enlargement A has a hollow screw-stem, B, on its lower end, which ispassed down the enlarged opening formed in the screw-stem O, usual tooil-cups, until the enlargement bears upon the bottom of the oil-cup D,when it is brought by the nut a, on the end of the screw-stem B,- takingagainst the end of the stem C, to form a perfectly tight joint.

If the joint be not perfect, from imperfect workmanship or other causes,a leather or other washer, b, can be placed over the stein B, betweenthe bottom of the enlargement and the bottom of the cup.

A part, c, of the surface of the enlargement A is faced oli", to formwhat may be termed a valve-seat, over which slides, perfectly tight, theshort arm d, of the spring-lever and valve E, which turns on a pin, f,fixed to the upper end of the enlargement.

A projecting pin, g, is fixed at the end of the long arm of the samelever'. M

Its end takes against a plate, F, which is in this instance shownfan-shaped, (though other shapes can be used,) formed or otherwise fixedto the enlargement, and projecting upwardly.

A duct, h, shown in dotted lines, iig.' 2, and in full black line in thesupplemental view of the same, which communicates the interior of theoil-cup with the channel k, cf the screw-stem B, has its opening in thevalveseat c, beneath the short arm of the lever E, which has ,acorresponding opening, l.

It will be readily seen that when the opening in the lever and the mouthof the duct coincide, the lubricant of the cup passes freely through theduct h, into the screw-stem B, thence to the parts to be lubricated.

The function of the pin g, taking against the plate F, is to throwforward the long arm of the lever, by which means the short arm springsagainst the Valveseat and forms a closer union.

It also by frictional contact prevents the lever from being casuallydisplaced when once regulated to pass.

4F,when combined and arranged as shown. e

3. The enlargement A, lever E, pin g, valve-seat c, and the plate'F, asshown.

In testimony whereof, we hereunto sign our names to this specification,in presence of two subscribing witnesses.
